NAME

sched_yield - yield the processor

SYNOPSIS

#include<sched.h>intsched_yield(void);

DESCRIPTION

A process can relinquish the processor voluntarily without
blocking by calling sched_yield. The process will then be
moved to the end of the queue for its static priority and a
new process gets to run.
Note: If the current process is the only process in the
highest priority list at that time, this process will con-
tinue to run after a call to sched_yield.
POSIX systems on which sched_yield is available define
_POSIX_PRIORITY_SCHEDULING in <unistd.h>.

RETURN VALUE

On success, sched_yield returns 0. On error, -1 is
returned, and errno is set appropriately.
